ATTORNEY WITNESSES UNITED STATES HARRY D. CURTIS, OF OSEKOSH, WISCONSIN.

SNOW REMOVER.

To all rv/mm it may concern:

Be it known that I. HARRY D. Culrris, a citizen of the United States,residing at ()shkosh, in the county of Winnebago and State of\Visconsin, have invented new and useful improvements in Snow Removers,of which the following is a specification.

This invention relates to snow plows for steam and street railways,trucks and the like and the principal object of the invention is toprovide spiral conveyor means for forcing the snow to one or both sldesof the track or road.

Another object of the invention is to provide blower means for receivingthe snow from the conveyor means for blowing to a distant point.

This invention also consists in. certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which-:

Figure 1 is a sectional view showing my blower located in front of alocomotive, the

section being taken on line 1-1 of Figure 2..

Figure 2 is a sectional view of one form of the invention.

Figure 3 is a sectional view taken on line 3-3 of Figure 1.

Figure 4 is a sectional view showing a modified form of the plow.

Figure'5 is an end view of this form.

Figure 6 is a sectional view of a further modification.

Figure 7 is a sectional view through this modification.

Figure 8 is a sectional modification.

Figure 9 is a sectional view through this modification.

In these views 1 indicates a casing which has its lower portion ofsubstantially semicylindrical form in cross section with its upper partinclining upwardly and outwardly as at 2. This casing is supported inany suitable manner in front of the engine or street car or othervehicle so that it will scoop up the snow from the track or road in viewof another Specification of Letters Patent.

front of the vehicle. As shown in Figure 1 the casing is attached to theengine by the arms 3. The lower edge of the casing is provided with anadjustable shoe 4 so that the shoe may be brought adjacent the surfaceto be cleared of snow. A shaft 5 is suitably journaled in the saidcasing and this shaft carries the right and left hand screwed conveyors6 which extend from a point adjacent the center of the shaft to the endsof the casing. This shaft carries a gear wheel 7 which is connected inany suitable manner with the source of power so that the shaft may berotated.

It will thus be seen that the snow scooped up by the casing will beforced towards each end of the casing by the conveyor blades and if theends of the casing are open the snow will-be deposited on each side ofthe track or road.

I prefer, however, to attach a casing 8 at each end of the casing 1 andto extend the ends of the shaft 5 through these casings. These extendedends of the shaft carry fan blades 9 so that a blast is created in eachcasing to drive the show delivered to the casings by the conveyorsthrough the outlet pipers 10 and the delivery pipe 11 which is connectedwith said pipes 10 by the rotary elbow 12. In this way the snow may bedellvered at any desired point or either side of the road bed.

In the modification shown in Figures 4 and 5 the ends of the casing 1may be left open so that the fan 9' will throw the snow from each end ofthe casing as the snow is delivered to them by the conveyors. I mayplace deflector plates 13 around the upper portion of the casing at theends thereof to prevent snow from being thrown back upon the plow or thevehicle. In this form a spider 14 is placed at each end of the casing tocarry the journals for the shaft In the modification shown in Figures 6and 7 the shaft 5 carries; but one conveyor blade 6 which delivers thesnow to one end of the casing. The gear 7 is located at one end of theshaft and a fan 9 may be connected with the other end so as to deliverthe snow received from the conveyor t0 the outlet pipe 10. I may usescooping side plates 15 at the ends of the casing for protecting thejournals and the gear and fan from the snow, said plates forcing thesnow to the conveyor. 4

It will thus be seen that driven through the snow on the track or roadthe conve or means will force the snow to each side the track or road orto one side thereof and if the blower device is used this snow can bedelivered to a distant point so as to remove the danger of the bankedsnow at the side of the upon the track.

In the modification shown in Figures 8 and 9 a double conveyor is usedwhich is so arranged as to feed the snowto the center of the casing. Afan casing is connected with the rear of the conveyor casing, at thecenter thereof, and the fan 21 therein acts to draw the snow fromthe'conveyor casing'and then discharge it from the outlet 22 at the topof the fan casing. This fan has its shaft 23 geared to the shaft 24 onwhich the conveyors 25 are carried. The fan shaft is connected in anydesired manner with a source of power.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily'apparent.

track falling back as the plow is guano? I desire it to be understoodthat I may make changes in the combination and arrangement of theseveral parts, provided that such changes fall within the scope of theappended clalms.

What I claim 1s:

1. A snow comprisin a horizontally arranged semicylindrica casing, a fancasin connected therewith, a spiral conveyor 1n the first mentionedcasing a fan in the. fan casing, means for actuating the conveyor andfan and an adjustable conduit connected with the fan casing.

2. A snow plow of the class described comprising a casing, a spiralconveyor therein formed of right and left hand parts and arranged tofeed the snow to the center, a fan casing in the rear of the conveyorcasing and connected with the center of said conveyor casing, a fan insaid fan casing, an outlet for the fan casing and means for driving thefan and the conveyors.

In testimony whereof I ,aflix my signature.
